Teenager held over murder of refugee centre worker in Sweden

A young asylum seeker has been arrested on suspicion of murdering a female employee at a refugee centre in Sweden.

The 22-year-old victim was stabbed to death at a centre for youngsters aged between 14 and 17 in Molndal, near Gothenburg, on Monday.

She was taken to Sahlgrenska University Hospital in Gothenburg, but died of her wounds.

Swedish newspaper Expressen named her as Alexandra Mezher, whose family was originally from Lebanon.

She had reportedly only been working at the centre for a few months.

"It is so terrible. She was a person who wanted to do good," a cousin told the paper.

"We have cried a lot. She was such a nice person, warm and happy."

Her parents described her as "an angel".

Police spokesman Thomas Fuxborg said there were signs of a violent fight at the home.

Two people were holding down the male suspect when police arrived at the scene.

He did not give any details about the suspect's age or nationality.

Swedish news agency TT reported he was 15-years-old.

"These kinds of calls are becoming more and more common," said Mr Fuxborg.

"We're dealing with more incidents like these since the arrival of so many more refugees from abroad".

Sweden's Prime Minister Stefan Lofven, who visited the centre, described the attack as a "tragedy".

"You should be able to feel safe at work," he said, according to the Gothenburg Post.

Sweden has tightened its asylum rules to curb the migrant flow after taking in more than 160,000 asylum seekers in 2015 - putting it among the EU states with the highest proportion of refugees per capita.
